Two interfaces, two IPs, nearly twice the speed?

[Federico Lorenzi]

Hi list

BACKGROUND:
I have two ppp interfaces tun0 and tun1 configured. Each of them
has an IP address in the same range, like 10.0.0.1 for the first and
10.0.0.2 for the second (They are really dynamic public IPs...). Now,
what I would like to do is get it so that they get mixed together.

QUESTION:
Is it possible to get PF to somehow round-robin the connections?
Lets say Joe connects to the internet and starts downloading a file,
it will use up Connection 1. Now Peter connects, PF knows that
connection 1 is used, and makes Peter's request go through
Connection 2. Kinda like a Dual-Internet?

Any help would be greatly appreciated!
